taking it 'old skool' TR HR-03 Rev. A, this is my specially modified for '4 card operation in a 759 Classified' version...
here
the heat sinks are Swifty MC21's, 8800 GTX styles. they have worked awesome with a number of cards, the 5870 included.
i run the card only for benching, 1050/1330 w/1.35v vCORE, stock volts on memory for now. core temps never crack 50C and the VDDC phase temperatures never go over 60C. a 120mm Ultra Kaze 2000RPM sits on the heat sink fins blowing down, with another pointed at the PCB near the rear of the card. i'll have photos of the card in action later tomorrow or the day after, i am running 2D right now.
